Hi,
I'm getting the following error when I run my Perl application
---------------------------------------------

---------------------------------------------
What I understood from this error is that the DB_File module is not
installed. So I tried installing the DB_File module. But then I get
the following error :(

---------------------------------------------
I couldn't find a proper solution for this problem. I saw some
suggestions of installing BerkeleyDB. But isn't that overkill. Do
we really need to install the DB_File and BerkleyDB modules to work
with Apache::ASP?
I also thought of using MLDBM::Sync::SDBM_File instead of DB_File.
But it's mentioned that
The output caching layer is a file dbm based output cache that runs
on top of the MLDBM::Sync so inherits its performance
characteristics.
With CacheDB set to MLDBM::Sync::SDBM_File, the cache layer is
very fast at caching entries up to 20K in size, but for greater
cached items, you should set CacheDB to another dbm like DB_File
or GDBM_File.
So will it be a good idea to use MLDBM::Sync::SDBM_File? Could you
please let me know how to resolve this Apache::ASP error.
Following is the settings in my httpd.conf file.
